Reliable’s Model KFR-CCS Combustible Concealed Space Sprinkler is a quick response, upright, specific-application sprinkler designed to provide protection of specific light hazard combustible and non-combustible concealed spaces requiring sprinkler protection. The KFR-CCS sprinkler complies with NFPA 13 criterion for the protection of combustible concealed spaces. The Model KFR-CCS Sprinkler utilizes a fast response solder-link fusible element. It has demonstrated response times in laboratory tests which are five to ten times faster than standard response sprinklers. This feature enables the sprinkler to apply water to a fire much faster than standard sprinklers of the same temperature rating.
Application
The Model KFR-CCS Sprinkler is designed for installation into: A. CPVC Pipe** – Wet Sprinkler Systems B. Steel Pipe – Wet or Dry Sprinkler Systems **The Model KFR-CCS Sprinkler is UL Listed for use with UL Listed CPVC Pipe and UL Listed CPVC Fittings. The allowable system construction types include: • Wood truss (12” to 36” deep) • Non-Combustible Bar Joist (12” to 36” deep) • Solid Wood (12” maximum depth) or Composite Wood Joist (12” maximum depth) • All systems are limited to an above-sprinkler (ceiling) horizontal slope of 2:12.
Model KFR-CCS The performance of the Model KFR-CCS Sprinkler in combustible concealed spaces was clearly evident during the full scale fire testing of this product. Concealed spaces between floors, as well as low pitch attics (slope of 2:12 or less) are inherently shallow. Standard spray sprinklers, by design, have an umbrella-like spray pattern that poses a difficult challenge when trying to achieve effective coverage within a shallow space. The Model KFRCCS Sprinkler addresses the difficult “above ceiling” fire challenge for both wet pipe and dry pipe sprinkler systems.
WARNING
Model KFR-CCS Combustible Concealed Sprinklers described herein must be installed and maintained in compliance with this document, as well as with the applicable standards of the National Fire Protection Association (NFPA), in addition to the standards of any other authorities having jurisdiction. Failure to do so may impair the performance of these devices. The property owner is responsible for maintaining their fire protection system and devices in proper operating condition. The installing contractor or manufacturer should be contacted with any questions.

Sprinkler Components
Fig. 1 **Note: In order to be considered “non-combustible, insulation filled, solid wood or composite wood joists” construction, the insulation (including insulation provided with a combustible vapor barrier), must completely fill the pockets between the joists to the bottom of the joists. Also, the insulation must be secured into place with metal wire netting. The metal wire netting is intended to hold the insulation in place should the insulation become wet by the operation of Model KFR-CCS Sprinklers in the event of a fire. In order to use the CPVC pipe and fittings, the horizontal runs of pipe must be a maximum of 6 in (0.15 m) above the ceiling or noncombustible ceiling insulation, or 1/3 the depth of concealed space (as measured from the top surface of the ceiling to the bottom of the deck above), whichever is smaller (Refer to Figs. 2 & 3).
The CPVC piping can then be used to supply the Model KFR-CCS Sprinklers, as well as the sprinklers installed below the ceiling. Unless modified by this technical data sheet, all other guidelines provided by the CPVC pipe and fittings manufactures must be followed. When using 1 in (DN25) or larger pipe, a hanger must be located at the truss nearest a sprig for purposes of restraint. If using 3/4 in (DN19) piping, all sprigs over 12 in (0.30 m) must be laterally braced using methods described in the NFPA standards. Where the CPVC must be offset up and over an obstruction and the pipe exceeds the allowed horizontal positioning requirements specified above as well as shown in Figs. 2 and 3, additional Model KFR-CCS Sprinklers are to be installed to protect the CPVC products. A minimum lateral distance of 18 in (0.46 m) must be maintained between the CPVC pipe and heat pumps, fan motors, and heat lamps. 2.
Concealed Space Area: The area of the concealed space is not limited; however, for both Figs. 2 and Fig. 3 where CPVC pipe is being utilized, draft-curtains or full height walls must be provided at 1,000 ft2 (93 m2) areas. This draft curtain shall be at least 1/3 the depth of the concealed space or 8 in (0.2 m), whichever is greater, and be constructed using a material that will not allow heat to escape through or above the draft curtain.
Remote Area: 1,000 ft2 (92.90 m2) (Note: Additional sprinklers that are required for protection of CPVC piping that is offset over an obstruction do not need to be included in the remote area.) Required Density: 0.10 gpm/ft2 (4.08 Lpm/m2) Minimum Operating Pressure:
Concealed Space Size: The depth of the concealed space is limited to 12 in (0.30 m) minimum and 36 in (0.91 m) maximum.
7 psi (0.48 bar) Obstruction Rules: All obstruction criteria per the applicable version of NFPA 13 apply, unless modified by this Bulletin (Refer to Fig. 7). The KFR-CCS is classified as an Extended Coverage Upright Spray Sprinkler when installed in locations where the maximum coverage area per sprinkler exceeds 225 ft2. The KFR-CCS is classified as a Standard Upright Spray Sprinkler when installed in locations where the maximum coverage area per sprinkler is 225 ft2 or less.

Installation Instructions
Model KFR-CCS Sprinklers are to be installed in the upright position with their frames arms parallel with the pipe’s run (Refer to Figs. 2 through 6). When installing the Model KFR-CCS sprinkler use only the Reliable Model D installation wrench. Usage of any other type of installation wrench may damage the sprinkler and will immediately void the manufacture’s warranty. Note: A leak tight ½” NPT (R1/2) sprinkler joint can be obtained with an installation torque of approximately 8 -18 ft-lbs (10.8 – 24.4 N-m). Do not tighten sprinklers over these recommended limits. Doing so may cause premature leakage and or operation.
Maximum Coverage Area Per Sprinkler: 196 ft2 (18.21 m2) for concealed spaces constructed of wood trusses or non combustible bar joists that are between 12 in (0.30 m) and less than 18 in (0.46 m) in depth. 196 ft2 (18.21 m2) for concealed spaces constructed of solid wood joist or composite wood joist where the concealed space is in between 6 in (0.15 m) and 36 in (0.91 m) in depth. 256 ft2 (23.78 m2) for concealed spaces constructed of wood trusses or non-combustible bar joists that are between 18 in (0.46 m) and 36 in (0.91 m) in depth.
Maintenance
Model KFR-CCS Sprinklers should be inspected and maintained in accordance with the applicable version of NFPA 25. Do not clean sprinklers with soap and water, ammonia or any other cleaning fluids. Remove dust by using a soft brush or gentle vacuuming. Replace any sprinkler which has been painted (other than factory applied) or damaged in any way. A stock of spare sprinklers should be maintained to allow quick replacement of damaged or operated sprinklers. Prior to installation, sprinklers should be maintained in the original cartons and packaging to minimize the potential for damage to sprinklers that would cause improper operation or nonoperation.
Note: Sprinkler spacing is determined by the depth of the concealed space at the location of the installation. When transitions occur in the concealed space, the sprinklers may immediately be spaced at the largest approved coverage area per the listing for the concealed space depth (Refer to Fig. 8) Deflector Position: 1.5 in (0.04 m) minimum to 4 in (0.10 m) maximum below the upper deck for concealed spaces constructed of wood trusses or non-combustible bar joists (Fig. 4). 1.5 in (0.04 m) minimum to 2 in (0.05 m) maximum be-
